For many researchers, the rhythm of the workweek has changed amid the COVID-19 pandemic. When you work from home, the days can merge, but scientists can build routines around regular events.

Aims To introduce a three-dimensional (3D) trajectory model that integrates structural and functional changes over time to ...

In this paper, we consider a nonparametric model with a time-varying regression function and locally stationary regressors. We are interested in the question whether the regression function has the ...

Structural models of default are widely used to analyze corporate bond spreads, but have generally been unable to explain why risk premiums are as high as they are. This credit spread puzzle can be ...
